About Us

At Zero Breast Cancer, we focus on modifiable risk factors—things that we can change—either individually or within our community. We recognize that social and economic conditions impact our ability to live in healthy places and pursue healthy behaviors. While many disparities are systemic, through education and empowerment we can increase our resilience and change our environments to improve the health of all.
